This is something i would like for a few sites too, on load buffer the video rather than autoplay it from the start but, im not sure how to achieve this, im guessing you would need greasemonkey and javascript knowledge but like i said im unsure.

Most sites have the play arrow over the video. I have no problems with these. If I want to play them I click on the arrow. It's those annoying videos that play automatically that irks me to no end. Often they are accompanied by text which I prefer to read as opposed to watching/listening to a video.

Everything is simple when you know how avatar lol but right now the documentation on injection is very limited with one example which does not make much sense to me but i'll look into javascript when im not browsing the internet, i take it i could change an element via adguard doing thenis then?

Say for example a flash video has autoplay=true could i change that to false?

Also is the injection rules limited in anyway like the extension rules are.
